EV batteries 10-50kWh. PHEV 4-16kWh. Charging via vehicle inverter – sinusoidal and bidirectional. Rates – SAE Levels 1 to 3. Conversion of Australia’s 11.5million light vehicles to pure electric would require 33,600 GWh in energy annually. The RET target is 45,000 GWh by 2020. The 24 hour average electrical demand would be 3.8 GW. AEMO has 44GW registered (Winter 2009) – east coast only. If charging is off peak and achieved over 8 hours – 11.4GW. A 1% vehicle fleet penetration – 114MW – 912MWhr. Rapidly dispatchable – i.e. sub-second.
